Creative Minds Created Something Cool?

I read the article about it last summer.  This was done with the support of a museum in London.  They set up a bathroom in the public place and you can enter the bathroom and could see everyone else around you.  You even can stare at persons who tried to take a peek inside the bathroom.
 
It was designed to permit the folks inside to see them outside whereas the voyeurs cannot see a thing inside the bathroom. 
 
Not bad? 
 
But not for me, I think I'd get conspitations if I try to squat and notice that guys were trying to detect me from outside. 
 

Enjoy the view?
